I'm in the process of filing my tax return online and am not sure if I've got the following thing right:
I'm self-employed. Last year I reduced my payments on account for the tax year 2013-14 because I was on maternity leave for 9 months of that year, hence I knew that my taxable income would drop significantly. So I reduced that payment to 400 pounds in total (numbers made up for illustrative purposes). Now, after having finished my return online I know for fact that I'll only have to pay 100 pounds of tax in total. The first payment on account in January was 200 pounds, the other one, due in July, will be another 200 pounds. So far so logical.
Now I'm wondering if it's safe to reduce my payments for the year 13-14 again, to 0 pounds, seeing as I've already paid off all my tax with the January payment? Does anyone know if that's ok to do or will it come to bite me in the back?
